Hi,
i just want to create with Ror an event when a the mouse is over an
element. Is there any helper function like link_to_remote that
generates the code....
I need something like this
<div onMouseOver="<%= function_i_need
''div_i_want_to_update'',
:url=>{:action=>''list''} %>" >
Some text
</div>
Thanks

You are close: look at ''link_to_remote'' source
http://caboo.se/doc/classes/ActionView/Helpers/PrototypeHelper.html#M005056
, and you''ll see that it calls ''remote function''
http://caboo.se/doc/classes/ActionView/Helpers/PrototypeHelper.html#M005063
In the view :
------------------
<a onmouseover="<%= remote_function(:url => { :action =>
:bar }) %>" >foo</a>
In the controller:
------------------
def bar
render(:update) { |page|
page.alert(''bar'')
}
end

When would doing something like that be useful or better than just embedding the javascript? Maybe if the stuff that you''d be mousing over was dynamic rather than static? Just curious.
